摘要
本文以我省小张庄村林网为研究对象,从林带结构与配置,林网在调节农田小气候,提高土壤肥力及粮食增产效果等方面进行了研究。结果表明,该村的林网结构与配置90%以上比较合理;干热风季节可平均降低风速47.7%,气温0.6-1.3℃,减少水份蒸发18.9%,提高相对湿度5.38—10.76%,小麦平均增产21.6%,有效地改善了农田生态环境,提高了抗御自然灾害的能力和作物产量,对该村的生态农村建设起到了促进作用。
The sheltelterbelt nets of farmland of Xiao Zhang Zhuang village in Ying Shang county, Anhui Province was selected as the object of study, The authors have investigated the structure and arrangement of the forest region,effects of the shelterbelt nets of farmland on regulation of local climate improvement of soil fertility and increase in the grain production. The results show clearly that more than 90% of the structure and arrangement of the shelterbelt nets of farmland in this village is reasonable. During the dry hot season the nets can decrease wind speed by an average of 47.7%, air temperature vvith 0.6-l.3℃, and moisture evaporation by 18.9%. It also can increase relative humidity by5.38-10.76%, wheat yield by an average of 21.6%. AH of these showed that the nets can eff iciently improve the farmland eco-environment and raise its potential in defence netural calamities and crop yields. It promotes the rural ecosystem construction in this village.
